Sense About Genetic Ancestry Testing
Many companies now offer to tell you about your ancestors from a DNA test. Adverts for these tests can give the impression that your results are unique and that the tests will tell you about your specific personal history, but the very same history that you receive could equally be given to thousands of other people. Conversely, the results from your DNA tests could be matched with all sorts of different stories to the one you are given: you cannot look at DNA and read it like a book or a map of a journey. This guide will help explain why, and what it is exactly that genetic ancestry companies are offering.
